Sodium Formaldehydesulfoxylate Dihydrate丨CAS 6035-47-8

Sodium formaldehydesulfoxylate dihydrate is widely used as a reducing agent, bleaching agent, and redox initiator across textile, polymer, chemical, and industrial processing fields. It plays a key role in textile dyeing and printing, where it is used to strip dyes, reduce vat dyes, and improve color uniformity during processing. In the polymer and plastics industry, it acts as a component in redox initiation systems for emulsion polymerization, enabling the controlled formation of polymers such as polyvinyl chloride, styrene-butadiene latex, and acrylic emulsions. It is also used in the formulation of adhesives, coatings, and synthetic rubbers. In chemical synthesis, it serves as a mild reducing agent for converting functional groups and stabilizing sensitive intermediates. Additionally, it is applied in water treatment, photochemical processes, and the preservation of certain chemical products by preventing oxidative degradation.

The main benefits of sodium formaldehydesulfoxylate dihydrate come from its strong yet selective reducing ability and its compatibility with a wide range of substrates. Its mild reaction behavior helps achieve controlled reduction without damaging delicate molecular structures, making it ideal for applications where precision is essential. In polymerization processes, it provides efficient initiation at low temperatures, supporting energy savings and stable reaction profiles. Its performance in textile processing improves dyeing quality, reduces defects, and enhances color consistency. The compound is also valued for its solubility, stability in storage, and predictable decomposition behavior, which contribute to reliable industrial performance. Its ability to prevent oxidation extends product shelf life and maintains the integrity of sensitive formulations.
